EOUNDABOUT 1 1` 'l p' Application ined Febreary `14, 1929.y `serial No. 339,340.

- vMy inveiitioirrelates'to iniproven'ients iii roundabouts, and it consistsA in the coinbinations, 1 constructions, and arrangements lhereindescribed and claimed. y .l

An ob'ect of my invention is to provide a roundabout which is` arranged to seat several children, and which has novel Vmeans wherebythe seat portion may be rotated.

A further object of my invention is tor provide a roundabout in which the seat portion is arranged to pivot at its center upon the rbase and the actuating member is pivoted to one yside of the center of the base.

A further object of my yinvention is to provide a device of the type described which is simple in construction, durable, andeiicient yfor the purpose intended.

Other objects and advantages will appear n a rions partsY of the device, the operation therein the following specification, and thel novel features of the invention willbe particularly a pointed out in the appended claims. n

My invention kis lillustrated inthe accompanying drawings, forming. part oi'.l this application, in which I Figure 1 is a side elevation oil my device,

portions thereof being broken away, and

Figui-e2 is a-section along the line of Figure 1.

ln carrying out my invention, l provide a base 1 which has a substantially horizontally extending member 2 provided with four projections which have their outer ends secured to the traiisversely extending legs 3 ot the base 1. Y

A disc 4 is'inounted upon the base 1 at. the centerthereof. An eccentric shaft 5 extends through the disc 4 and has the vlower yendk rigidly secured to the member 2. A collar (3 is disposed concentric with the shaft between the member 2 and the disc 4, A supporting arm 7 is carried by the upper end ot the eccentric shaft 5.

A rotating member 8 is provided with'an annular vseat portion 9 having inwardly entending connectingarms 10 which have their inner ends secured to a-bearing, support 11. Roller bearings 12 are carried by the bearing support 11v and arranged to engage with` the peripheral edge of the disc 4. v C3 Upwardly extending brace rods 13, which have their lower ends secured to the connecting arms 10, have their upper ends secured yto a top member 14..y A pivot screw 15 is carried by the top member 14'aiid has its conical-shaped end` received in a conical-shaped `recess in the inner end of the arm 47.

A n actuating member 16 is provided with yan annular gripping member 17 which is connected to asleeve 18 by means of bars '19. The 'sleeve 18 is disposed concentric with the shaft 5 Vandis rotatable with respect thereto'.` Atensio-n spring 2O is provided' for normally'holding the actuating member 16 .in its rotative position with respect to the rotating member 8.` An annular footiest 21 is carried by the rotating member 8 and positioned beneath theseat portion 9. Fr'om the foregoing description of the va ofanay be readilyunderstood. Any number of persons that may sit' upon the seat portion 9 may actuate the device. To start the member 8 rotating, the person .sitting at the point indicatedy at X would push upon the actuating member 16 and the' person sitting at thej position indicated at Y would pnll upon the actuating member ll In tliis'mannerv the rotating member 8 would start rotating in a clockwise direction.y

upon the actuating member 16. The actuat-` ing member 16 will rotatewith the rotating member 8 but vabout aA dii'ferentcenter.` This different center enables the device to be readily actuated. As the member 8V is rotated, it is 'supported by the sha-ft 5, lbut does not rotate about the cent-eroi the shaft. Therefore', there'is an' oscillatory movement as well l.,-

as a rotative movement of the actuating meinbei 16. :f v l .f Y' i "It may be observed that the device has only `two'. movable parts; namely, the rrotating member 8 and the` ractuating member 116. Furthermore, the device' may be actuated not only by vthe* pulling'of one person upon one side and the pushing by another person di'- rectly oppositejbut it may be actuated during therotative movement thereof by all the persons seated thereupon with the exception of the two persons Who are seated opposite the vertical shaft 5 when the actuating device is at dead center. By viewing Figure 2, it Willbe noted thatthe dead center lineis directly across the horizontal center line of the device. Therefore, any persons seated around the device, .With the exceptionof the Vtwo points upon the i horizontal `center line,

may, While the device is in this position, aidin actuating the device. The point is that ali persons mayV at all times during the revolution of the device aid in actuating the device with the exception oi the-tivotimes when they are positioneddirectly at the deadfcenter points. Furthermore, in view of this jlfact, the 'device may readily be stopped and readily rotated in the opposite direction. Y

I claim:

l, A device of the kind described embodying therein a base, an annular member on said base, an uprightmember arranged eccentrically of said annular member, a seating means supportedA on said upright meinberor rotation concentric With respect. to said annular member, `means carried .by said seating means for a guiding engagement with the periphery of said .annular member and an` actuating member rotative on said upright member but leccentric with respect-to said seating member.

`to said base, an upright member fixed to said "base'and extending through said annular member but on' center thereof, `an annular seat arranged concentric with respect to said annular member, a cap member pivot-ally mounted on said upright member concentric fwvith-said annular member, arms connecting said seat and cap.` members, other arms extendinginwardly*from the seat member and fari-ying rollers for peripheral ,guiding cngagement with said annular member and au annular actuating member rotative about and supported by said upright member.
